Through bolt anchors or through bolt are same as wedge anchors, as one of deep-buried steel expansion anchors,designed to increase the load value. Expanding through bolt achieve greater tensile strength than ordinary inserted bolt, more suitable for the holes with unknown depth. Steel through bolts are ideal for fixing and installing applications, where the expansion anchor spacing and edge distance are closer than some steel plug-in anchors.

    Concrete through bolts is composed of a nut, a washer and an expanding clip wrapped around conical rod body, will expand in the downward direction of the wedge body when the hex nut is tightened, resulting in expansion force to achieve easy and quick installation, throughbolts are produced in metric and inch size standards to meet different market demands.    

[Product Features]:

▲ Design full or long external thread to make the fixing height of the object adjust more easily.

▲ Also called throughbolt or throughbolt anchors.

▲ Don't require precise drilling hole depth.

▲ Enable to hammer it to the below of the substrate if being no longer needed.

▲ Being suitable for medium-heavy duty loading purpose.

▲ Steel expanding clip is completely wrapped anchor wedge body to ensure the full expansion force and tensile strength and prevent it from twisting and falling off in the hole.

▲ Shrunk-convex head design protect external threads from damaging when hammering.

▲ Provide American Unc-thread and Metric mm-thread standard.

[Installation Steps]:

(1). Drill a hole in the base material to ensure the proper diameter and depth required.

(2). Use a nylon brush to remove all debris and dust.

(3). Pass through bolt body through a guide hole in the object and vertically align with a drilled hole in the substrate.

(4). Hammer the head to insert into the hole.

(5). Fasten the hex nut by tool until being fully fixed.
